Ordinance to keep drivers from going off the deep end

Tucsonans could find out just how expensive getting rescued is this summer thanks to a city ordinance that penalizes drivers who ignore flash flood warnings in washes and underpasses.

The ordinance went into effect last year because of the many people who have had to be rescued in the past, said Captain Brian Delfs of the Tucson Fire Department.

"They're not only putting themselves in danger, but also the rescuers," Delfs said.

Drivers who disobey the warnings will be cited for a civil infraction and fined $50, Delfs said. Also, he said the cost of a recovery rescue can range anywhere from $104-$390, depending on how many rescue units need to respond.

A standard swift water response requires six fire department units which could total over $1000, Delfs said.

While tourists usually obey the signs that warn against driving through flooded underpasses, he said Arizona residents often ignore warnings because they are in a hurry to get home.

"People from out-of-state don't take anything for granted," he said.

Last year, two people were rescued from flooded underpasses while dozens of others had to be saved from flooded washes, Delfs said.

Flash floods occur when rainfall is so rapid, the ground is unable to absorb it quickly enough, said Andy Bryant, hydrologist for the National Weather Service's Tucson branch.

Bryant said very intense rainfall could result in an inch or more of rain within 15 minutes.

Heavy rains are in the forecast for later this week, he said.

"Conditions are continuing to improve for us to get thunderstorm activity," Bryant said.
